Product Overview

Introducing Doctor’s Best Natto-Serra dietary supplement! Specially designed to promote healthy immune responses, boost circulation, and maintain blood pressure levels, this could be exactly the supplement you need!

What does Natto-Serra stand for? Well, these third-party tested capsules are crafted from a combination of 2 natural enzymes. Their names? Nattokinase and Serrapeptase - that’s where the snappy title for these capsules comes from. These are protein-digesting enzymes that have gained a reputation for being a fantastic supplement. Only the best for our customers!

The casing for these capsules has also been formulated with thought. It’s not only vegan but has also been selected to allow optimum absorption into the body - pretty neat, right? 

This supplement is also gluten-free and non-GMO, so it ticks all the right boxes for us!

Frequently Asked Questions

Where do Nattokinase and Serrapeptase come from?

Nattokinase and Serrapeptase are two natural enzymes that have been used for many years as dietary supplements. Serrapeptase is actually derived from the Japanese silkworm, isolated from the friendly Bacterium Serratia E-15. 

Nattokinase comes from ‘natto’, a fermented soy product also from Japan. So, these protein-digesting enzymes both come from natural sources to promote natural health in your body!
